Creating A Web Application Project Using Command line (.NET CLI)

Creating A Web Application Project Using Command-line (.NET CLI)

This tutorial shows step-by-step instructions to create an ASP.NET Core Web Application Project with individual user authentication.

I use the Windows Power Shell command interface for this tutorial.

At the time of writing this tutorial latest available .NET Core version is 6, while Visual Studio 2022 community is the latest available version. But I wanted to use and test an older application and custom template build using ASP.NET Core 2.2 and Visual Studio 2017. And I wanted to create several test projects but the old custom templates didn't work. And also most of the Microsoft documentation is changed, updated, or outdated. So most latest documents are based on the dotnet new command line. So I wanted to dig into the dotnet CLI. I know that this will be useful for me again later time or it will be useful to someone else. 

Create directories 

First, we create a directory for the template
PS D:\dev\dotcli> mkdir myTmpBox\templates
PS D:\dev\dotcli> dir mytmpbox



List installed dotnet versions

In my development computer, there are several dotnet SDKs are installed. To find out what they are use the list-SDKs option.

PS D:\dev\dotcli> dotnet --list-sdks



Show the current version and more information about installed SDKs


The current version is 6.0.0. But we want to create a project for the older version 2.2.

Working on an older version

We need to switch to the older version. we can just make the working root folder work on the older version by using the command globaljson . 

PS D:\dev\dotcli> dotnet new globaljson --sdk-version 2.2.108 --force
Note the word globaljson,  there is no dot before json. After executing the command it will generate a file named global.json. 

For detailed instruction read Work on a lower version of dotnet core.


Create A New Razor Web App Project With Individual User Accounts

PS D:\dev\dotcli\MyTmpBox\templates> dotnet new webapp --name RPWebApp1 --auth Individual




Create A Solution File

The project is created but there is no solution file. We have to create a new solution file.

PS D:\dev\dotcli\MyTmpBox\templates> dotnet new sln --name Razor22

Then add the previously created project to the new solution

PS D:\dev\dotcli\MyTmpBox\templates> dotnet sln add RPWebApp1\RPWebApp1.csproj


Now we have created an ASP.NET Core 2.2 Razor Page web application using dotnet template engine command-line tools.

Open the solution file (Razor22.sln) using Visual Studio 2017 Community Edition


Projects with individual user accounts (ASP.NET Core Identity) created using dotnet new command, create a Sqlite database. If we create a project with individual user accounts (ASP.NET Core Identity)  in Visual Studio 2017 it will use  MS SQL Server local Db  instead Sqlite. 

Run the Web Application by pressing Ctrl + F5



Conclusion

In this tutorial, we learn how to create a Web Application using dotnet new template engine as well as several other important commands like  globaljson  and sln .

Figure 1: Solution Explorer -Top-level view When using the wizard, there are a few options to choose from. The final generated project code and structure depend on these selections. For example, if a project is created using the AS

Displaying A Start Page In ASP.NET Core 3.1 Web API Project.

Displaying A Start Page in ASP.NET Core 3.1 Web API project. When we create a Web API project using Visual Studio 2019 Template there is no file to display when the web application start. That is because Web API doesn't need to display any information to the user or the public. But some times we may need to add a little bit of information to the site, or even during the development stage we may need to show some information. Add app.UseDefaultFiles(); app.UseStaticFiles(); to the Configure method in the Startup.cs file. Then Add a Folder and name it as wwwroot . This is is very important. Then add the Index.html file inside wwwroot folder. Now we can edit the index.html file to add any information. That's it.
